spelling Alvarez, Víctor H.Silva, Silvana Mattedi eAznar, MartinAlvarez, Víctor H.Silva, Silvana Mattedi eAznar, Martin2013-11-08T18:28:56Z20130021-9614http://repositorio.ufba.br/ri/handle/ri/13596v. 62p. 130–141This paper reports the densities, refraction indices, and vapor liquid equilibria for binary systems ester + N-methyl-2-hydroxyethylammonium butyrate (m-2-HEAB): methyl acetate (1) + m-2-HEAB (2), ethyl acetate (1) + m-2-HEAB and propyl acetate (1) + m-2-HEAB (2). The excess molar volumes, deviations in the refraction index, apparent molar volumes, and thermal expansion coefficients for the binary systems were fitted to polynomial equations. The Peng–Robinson equation of state, coupled with the Wong–Sandler mixing rule, is used to describe the experimental data. Since the predictive activity coefficient model COSMO-SAC is used in the Wong–Sandler mixing rule, the resulting thermodynamic model is a completely predictive one. The prediction results for the density and for the vapor–liquid equilibria have a deviation lower than 1.0% and 1.1%, respectively. Highlights ► Densities, refraction indices and VLE were measured for ester + m-2-HEAB mixtures. ► VE, apparent molar volumes and thermal expansion coefficients were calculated. ► Peng–Robinson EoS + Wong–Sandler mixing rule + COSMO-SAC predicted the data.Submitted by Santiago Fabio (fabio.ssantiago@hotmail.com) on 2013-10-29T18:45:38Z No. of bitstreams: 1 3333333.pdf: 1049559 bytes, checksum: 3a80fb413a811163c82948b48e38df55 (MD5)Approved for entry into archive by Rodrigo Meirelles (rodrigomei@ufba.br) on 2013-11-08T18:28:56Z (GMT) No. of bitstreams: 1 3333333.pdf: 1049559 bytes, checksum: 3a80fb413a811163c82948b48e38df55 (MD5)Made available in DSpace on 2013-11-08T18:28:56Z (GMT).
